Patented Oct. 5,. 1937 PATENT OFFICE ROTARY MACHINE FOR DYEING AND WASH- ING TEXTILE MATERIALS Juan Rabassa,-Barcelona, Spain Application July 19, 1933, Serial No. 681,053 7 In Spain April 26, 1933 2 Claims. (01. 819) The machine according to the invention is of special application in the dyeing and the washing of textile materials especially stockings, skeins and other small articles; it has a rotary action and comprises a central reservoir for the dyeing liquid or for the washing or other liquid to be used in the treatment, and radially disposed'containers provided with valves in corresponding positions to establish or break communication between the said containers and the central reservoir. The materials to be treated in the baths of treating liquid are introduced into the radially disposed containers.

The rotary movement. of the central reservoir with its radially disposed containers causes the textile materials to be continuously and thoroughly washedor stirred in the liquids in the containers in 'the treatment, the thoroughness of the washing or stirring of the textiles with the treating liquid determining the efiicacy of the treatment.

A machine constructed according to the invention, is diagrammatically illustrated by way of example in the accompanying drawings.

Figure 1, is a front elevation of the machine according to the invention.

Figure 2 is a corresponding side sectional elevation.

Figure 3 is a detail view on an enlarged scale tainers.

The machine comprises two frame members I and 2, supporting at their upper ends bearing blocks 3 and 4 on which a tubular shaft 5 pierced with holes 6 is mounted to rotate. A reservoir 1 for the treating liquid is formed integral with a tubular shaft 5 to rotate with it, and carries secured thereto'containers 8, 9, II), II, I2, and I3 which. are radially disposed with respect to the tubular shaft -5. The containers hereinbefore mentioned are secured to the central reservoir I by means of draw bolts such as I4, I5 (Figure 3). Each of the containers 8, 9, II], II, I2, and I3 is fitted with a metallic gauze filter I6 and, moreover is provided with a valve I8 fitted in an opening I! andoperated by the aid of an eccentric IS, a spring being provided on the valve stem to ensure that the valve stem bears againstthe eccentric. Each eccentric I9 is mounted on a transverse arm or spindle 2| with which there is integrally formed an angle arm member 22. On the' tfixed part of-the machine are disposed two projecting abutments 23 and 24, for co-operating with the angle arm members 22 to open and close the valves l8. The

in section of oneo'f the radially disposed conabutments 23 and 24 may be put out of action when desired with respect to the arm members 22 by being withdrawn in a direction away from the machine. 25 is the receiver containing the dyeing liquid or other liquid which is raised to pass through a pipe 26 under the action of a. pump 26 through the tubular spindle 5 into the central reservoir I through the holes 6. The water necessary for the formation of the bath with the said dyeing liquid or other liquid may be introduced through the pipe 28. Through the pipe 2i steam is also led to the central reservoir I for heating the bath and for producing a pressure adapted to favour the treatment of the articles.

Each container such as 8 comprises an atmospheric valve 29 which operates to prevent the formation of a vacuum, when the steam contained in the container 8 is condensed. The valve 29' is provided in a dome-shaped cover 32 by which the, container 8 is closed in the use of two wing j'nuts such as 33, 3! applied on the extremities of the draw bolts I l, l5.

The rotary reservoir 1 comprises; moreover, three pipes 33, 3 3, and 35 leading from the machine and provided with cocks 36, 31, and 38 respectively, operated by angle arm members 39, 40, and 4|, by means of end pins 42, 43 which may be rendered inoperative by withdrawal in a direction away from the machine.

After having filled the containers 8, 9, I0, II, I2, and I3 with the articles to be dyed or to be washed, by opening the covers 32 and closing them as soon as the articles have been put in, and after having introduced the treating liquid into the central reservoir 1, the reservoir 1 with the radially disposed containers 8, 9, III, II, I2, I3 is rotated; the valves I8 will remain open so that the radially disposed containers may be in communication with the central reservoir. This result is obtained by placing the abutment 23 in the operative position and the abutment 24 in the inoperative position, the radially disposed containers will then fill with liquid when they take up the position with the openings I'I uppermost, and will empty successively when they take up the position with the openings Il downwardly directed. 'In this way the effect will be obtained that during the operation of the machine, liquid is passed into and out of the radial containers and a thorough stirring of the liquid with the articles being treated takes place, which will efiectively dye or wash the articles, in the use of only a small quantity of treating liquid, this being one of the principal advantages of the machine.

When, the treatment being finished, it is desired to empty containers 8, 9, M, II, II, and I3 and to stop the. flow of liquid into them item the central reservoir I, the valves it will have to be opened when the containers are uppermost with the openings l1 downwardly directed and closed when the containers are in the opposite position;

this is effected by placing both .the abutments V 23 and 24 at the same time in the operative positions.

The pipes .33, 34, and serve to permit the escape of steam from the reservoir 1 when it'is' desired to lower the pressure-in the same. and for this purpose the pins 42 and 43 are placed in the operative position, then the cocks 36, 31, and 38 are open when the angle arm members 39, 40, and 4| abut against the pin 42, and close when the pin 43 bears against the passing out to the atmosphere-during the travel;

from the pin 42 to the pin 43, that is=tosay, during the desired number oi revolutions.

These pipes 3:, '34, and false serve to empty of liquid the central reservoir 1 when the treatsuch as 45, liadapted to serve asideflectors e1 7 the =articles int'rpduced into the containers so that they maybe subjected to violent changes of position to render more eiiective'the' application 7 of the treating liquids duriniithe rotary movement oi-the containers.

The machinehereinbefore described affords the advantage, as has been hereinbei'ore mentioned, that the dyeing or washing is elected in the use of a small quantity of treating liquid, as this is mixed distributively on the article under treatment when the liquid is vely in and out of the radial containera I claim:
